Hearing loss can make Sara Sjostrom even faster – New Technology

Water-around swimmer can be listened to and be a tool to increase speed.

At the Olympics in Brazil took Sarah Sjostrom gold in the 100 meters butterfly stroke and set a new world record winning time 55.48 seconds. 16 hundredths better than the previous record.

Now, say researchers at the University of Bielefeld in Germany to a new training method can make swimmers faster. They turn the water pressure and currents around the swimmer to the sound in real time listened to through headphones in the basin. Then the swimmer can listen to the changes in simsättet that increase the speed, writes the University.

The water flow is measured by sensors in a pair of gloves that the swimmer wears. These data are linked via a cable to a measuring device which converts the variations in the flow of water over the gloves to the audio signals are sent to the swimmer.

– When the swimmer can listen to the changes in water pressure, he can get more power without effort more, says biochemist Bodo Ungerechts at the University of Bielefeld.

in retrospect, even the swimmer listen to the recorded sound of a particularly fast pool length and memorize the “melody” that gave maximum speed and try to emulate it at the next round of training.

It is a great advantage to have immediate feedback when learning time is much faster, writes the University.
